Zenodo is a general-purpose open-access repository developed under the European OpenAIRE program and operated by CERN. It allows researchers to deposit research papers, data sets, research software, reports, and any other research related digital artifacts. For each submission, a persistent digital object identifier (DOI) is minted, which makes the stored items easily citeable.
Zenodo was created in 2013 under the name OpenAire orphan records repository to let researchers in any subject area to comply with any open science deposit requirement absent an institutional repository. It was relaunched as Zenodo in 2015 to provide a place for researchers to deposit datasets; it allows the uploading of files up to 50 GB.
In 2019, Zenodo announced a partnership with the fellow data repository Dryad to co-develop new solutions focused on supporting researcher and publisher workflows as well as best practices in software and data curation.
